the art to which it appertains to make and use the same.

The general object of this invention is to improve the construction andincrease the capacity and efficiency of machinery for making combinationpaper board, more especially board composed of one or more phes'mfcorrugated'paper or paper board with or Without .one or-more smoothfacing sheets. 3

A particular object of the invention is to provlde for corrugating oneor more sheets of paper at the same time, pasting them together, ap'lying one or more facing sheets I as desired, rying the composite sheet,and slitting or trimming, scoring and cutting the material into desiredlengths, all in one continuous operation.

Another particiilar object is to provide a highly improved travelindrying apparatus for drying the eomposite si cation, and then moreparticularly pointed.

Figs. 9, 10 and 11, taken together, show a side elevation of theentire machine looking'at the opposite side to that indicated in Fi s.2, 3 and 4, and representing correspon ing sections of the machine.Fig-.12 is an enlarged vertical section through one of the aste boxes.Fig. 13 is an enlarged detai side view, with parts in section, of aportion of one of the endless traveling drymg belts or a rons. Fig 14 isa top plan view of the su )ject-n'iatter of Fig. 13, partly insection.

At the front of the machine,nlounted in a suitable stand or rack- 1, area plurality of supply rolls of paper, preferably three rolls designatedA, B and C, from which respective sheets of paper'are ai'lapte-d to beunrolled and drawn rearward in alin ement with each other. The shafts 2on which the said rolls of paper are mounted are shown equipped withpulleys 3, keyed or fast on said shafts, said pulleys being frictionallyengaged by weiglhted straps 4 or'stri is of leather, canvas or t e like,acting as bra tees to retard the rotatiom of the rolls and prevent thesheets of gaper from feeding faster than they are rawn through themachine. For insuring the feed of the several sheets of paper in correctalinement, the usual or any appropriate adjusting devices may beprovide" In this connection, the illustrated hand-wheels 5 are intendedfor shifting or adjustingthe rollshafts 2 transversely, while thehand-wheels 6 are intended for ad'usting said shafts axially, the saidhandeels operating adustbearings.

According to-the illustrated embodiment of m invention, the roll A isintended to 'su p y a'smooth sheet of paper, while the ot er rolls B andU are intended to supply corrugated sheets --to be pasted together andto be faced on one side by the smooth sheet A, also to be faced on theop osite side by a fourth sheet of pa er'hereina ter mentioned, Incarryinglout t is urpose, the sheet B from the middle roll of g screwswhich engage the movable s aft paper is drawn rear-' ward through acorrug'at'ing mechanism,

or intermeshing fluted or corrugated rolls,

' preferably three of such rolls designated 8, 9

rearward the same time.

and 10. The paper sheet B passes successively between rolls 8 and 9 andthe rolls 9 and 10, as shown in Fig. 2, wherebythe corrugations in thepaper are first formed and then more permanently set. The ressurebetween the corrugating rolls may e regulated'by adjustingscrews 11bearing upon pressures rings 12, the latter being seated upon theearings of the topmost corrugating roll, which bearings, together withthose of the middle corrugating roll, are vertically movable oradjustable in guide-ways therefor in the stand or rack 7. The rolls maybe heated by any appropriate means, as by steam, gas or electricity, butas steam is enerally used by the manufacturers, I have 11 ustratedsuitable s'team econnection in Figs. 6 and 9, wherein 13 and 14designate valved steam sup ly and exhaust pipes in communication wit thehollow trunnions of the several cor-- ru ating rolls, said rolls beingalso hollow.

ehind the corrugating rol s 8, 9 and 10 is a stand or rack 15 supportinga similar set of corrugating rolls 16, 17 and 18, provided with similaradjusting means (screws 11 and springs 12) and steam supply and exhaustp pes 13 and 14 for heating. The sheet C m the lowermost roll of paperis drawn, past a guide-roller 19 and carriedv between t e corru'gatingrolls 16, 17 and 18 in the same manner as the sheet B is carried sheetsare drawn rearward and corrugated at Both sets of corrugating rollsareshown longitudinally fluted for corrugatin both sheets B and Ctransversely of the wi ths of the sheets. But, if desired, one set ofcorrugating rolls may be annularly orperipherally corru ated forcorrugatin the sheet longitudinal for the purpose 0 making twocorrugated sheets at one time with'corr-ugations' crossing each other,which would be advantageous in some cases where a very stiff material isrequired. In case of corru atin one sheet longitudinally, it would beesirable that the sheet should be initiallywider than the other sheet,and the mechanism for making the longitudinal corrugations shouldpreferably be preceded byor contractin appropriate means for atheringthe paper its widt to accommodate the amount 0 paper taken up by thelongi tudinal corrugations.

The smooth sheet A to ether with the two (which latter ass from theirres ective 'corrugating' mec anisms over suita ly-disposed guiderollers20) are drawn rearward over or in contact with a set of paste-rolls 21,which are-arranged in paste-boxes '22- holding the paste, glue or 'ad-'esive mixture for applying to the. sheets of Thus the two.

' with the other sheets.

1 and 3) shown mounted-behind the roll paper. Said paste boxes 22 areshown mounted one above another in a rack .or stand 23 and can. bewithdrawn laterally from the side of the machine shown in Fig. 2.Associated with each pasteroll is aparallvl small roll 24 for spreadingthe paste or g1 ue evenly upon the larger aste-roll, so that it will heapplied uniform y'upon the surface ofthe pa er. Above each paste-roll isanother sma 1 roll 25 forthe purpose of holding the paper down firmly onthe asteroll.

1 The small roll 25 can be lifted 0 when it is desired to withdraw-thepaste box. The bearings of the paste-roll 21 and spreadingrolls 24 arecontained wholly wlthin the paste-hoxes,'so as to keep the aste fromescaping and soiling the mac line. The paste-rolls are also heated,preferably by steam, for which purpose said pasterolls are made hollowand are shown in communication with steanisupply and exhaust pipes 26and 27 in Figs. 6 and 9, packing-glands being provided between thesteam-connections and the hollow journals or trunnions of thepastcrolls.

' On leaving the paste-rolls, the several sheets A, B, C, with adhesivecoatings ap-- plied to their respective under sides, are drawn rearwardpast guide-rollers 28 and between co-acting press-rolls 30, which lattermay be slightly roughened or corrugated as circumstances may require.The pressure between the press-rolls 30, in the illustratedconstruction, is furnished by the weight of the upperroll which bearsupon the lower roll, the bearin s of the upper roll being car ried byweights levers 31. Below the pressrolls 30, the sup orting rack oistanll29 also supports a simi ar set of press-rolls 32, the pur 5 se of whichwill appear later,

ehindthe press-rolls 30 and 32, a "fourth supply roll of ppper D ismounted similarly to t erolls A, and C. Said roll D is provided forthepurpose of supplying another smooth facing sheet at the under side ofthe sheets furnished by the three rolls A, B and C the sheet D beingdrawn from itsroll and. carried between the press-rolls together Anotherro'll E (Figs.

D, and is placed there merelyilrfor the purpose of continuing the feedof t e under facing sheet when the supply of the roll D is ex hausted.

By assing through the press-rolls 30, the

severa sheets 01'' plies of paper become ressed andstuck together, thepaste or ad esive mixture havingbeen applied to the under sides of thesh'eets A, B and C, so that the adhesive coatiii comes between theseveral confronting .s eets or. plies of paper. .The thick compositesheet orgreen board so formed, indicated by the letter .F, is then drawnrearward through another set of press-rolls 33 (Fig. 3), shown in thisinstance runs of the belts level and ss7,co7

equipped with pressure-springs 34 and ad justing screws 35. Saidpress-rolls 33 serve not only to press the composite sheet, but

also to feed it rearward to the traveling driers and to draw the severalconstituent sheets through the machine.

It will be noted that in practice any one or more of the several sheetscan be omitted or dropped from use, sothat it is possible to'run eithertwo'corrugated sheets, or one or more corrugated sheets with a smoothfacing on either one or both sides. If it be desired to run only asingle corrugated sheet and single smooth sheet together, the lowercorrugated sheet C and the smooth sheet from the roll D may be broughtthrough the press-rolls 31 as indicated by 'dotted lines in'Fig. 2. Suchmodifications as placing the supply-roll D above instead of below theress-roll 31 and arranging for corrugating tlie sheets A and B insteadof B and C, or for corrugat/ing the sheet (7 in advance of thecor'rugating of the sheet 13, and other modifications in the gen- .eralconstruction and arrangement, would of course'fall ,within the scope ofthe invention.. g

On leaving the press-rolls 35, thecomposite sheet or green board Fpasses to and is operatedlupon by a traveling drying apparatusshown inFigs. 3, 7, 10, 13 and 14, which dries the material in transit and whilepressing it out fiatwise, therebyavoidin bending and consequent injuryto the sti board, and carrying out the drying process as fast as thematerial is produced and in one continuous operation with thecorrugating and pasting processes. Saiddrying apparatus comprisescoacting endless'belts or aprons 36 and 37,. each composed of a seriesof hollow pans or boxes 38 hinged -or flexibly-connected together so asto move freely around the ends of turns of the belt, but so that theco-acting runs of the two drying-belts or aprons form practicallycontinuous flat surfaces Whichwill hold or press the green board ormaterial fiatwise between them Said hollow pans or boxes are providedon'their ends with pairs of small Wheels or rollers 39,- which bear uponand travel over and around suitable tracks 40 which hold the horizontalguide the belts properly around their turns. Said tracks 40,constituting the supporting and guiding means for the drying belts oraprons, are shown mounted between the uprights 41. Each drying belt isdriven from one end-by' lateral spur-wheels.4 2, the-teeth ofwhich ena e.between'the pairs of smallwheels or These endless drying belts heatedby steam (or other hdt flui passing the-hollow pans or boxes, the meansfor w 'ch purpose are shown iii-Figs. 3' and 7,;

rol ers 39 'on the ends of the holloW pans. Adjustable bearings forthe-spur-wheels permit adjustment or tension'ing ofthe belts.

or aprons are f circumstances so that t and more clearly in Figs. 13 and.14. At one side of the drying apparatus, substantially midway thereof,a steam supply-pipe 43 is connected by a flexible pipe or hos'e section44 with one of the hollow pans or boxes of each drying-belt, the lengthof the hose section 44 being suflicient to maintain connection betweenthe steamsupply-pipe 43 and said hollow box .during the complete circuitof travel of the latter. The said hollow pan or box into which the steamenters may be designated 38. At the opposite side of the dryingapparatus, an exhaustpipe 45 is connected by a similar hose section 46with an adjacent box or pan of each dryin -belt,

which box may be designated 38 T e several hollow pans or boxes areconnected in series by short hosese'ctions or flexible pipe connections47, each coupling one box with the adjacent box, except that there is nosuch obnnection between the boxes 38 and 38*. In this manner, the livesteam enteringthe box 38 will ass successively through all the boxes andally exhaust from the box 38"; the incoming steam pushing out theexhaust steam behind it.

As shown in Fig. 14, the flexible connections or hose sections 47 arealso arranged alternately at opposite ends of the hollow pans or boxes38, so that the steam is sure to pass throughout the boxes and heatthem' uniformly. The flexible hose connections 47' between the boxes.will bend freely as the drying belts are making the turns, while thehose-sections 44 and 46 connecting with the steam inlet and exhaust pies 43 and 45'will follow the drying belts in all positions. The severalllOSG'SBOtlOIlS-ITIBY be of rubber, fabric or any flexible materialsuitable for the pur- Y pose.

The object of the above described drying apparatus is to dry corrugatedf paper, or paper board, -mill board or any sti material that cannotproperly be bent or warped while. drying,. and for drying the same intransit, or as fast as the material is produced and fed to the driensoas to carry out, the drying process as a continuation of the operation.of making-the material in the green state. The drier is not limited inits useful applications to'the particular machine herein set forth. I

The dr ing apparatus can be arranged horizonta ly,-ve'rtically, or insuch other position as the. case may require, and may if necessary bebuilt in one or more sections so that any desired amount of' heat can besecured in the driers at different points. They can be built in such away-that the first'section would press the paper at different points, I

while the second section would press the paper passed by the firstsectiomand so on. should require it, the driers could-be'lplaced a shortspace from eachother e moisture wbuldevaporate freely.

- volving As the material is. delivered or emerges" from the travelingdrying belts, it passes between press-rolls 48, which serve to press thesheetand also'to help drag the material through the machine and force itrearward through the slittingand scoring rolls and cutter. Saidpress-rolls 48, mounted in a stand or rack 49, are shown provided withpressure-springs 50' and adjusting screws 51.

From the press-rolls 48, the material passes between enacting slittingwheels or disk shears 52 and 53, which are for the purpose of trimmingor cutting the paper'the desired width or widths as it passes along, andthence between co-acting soorin wheels 54 and 55 which mark the materialongitudinally so that it will fold readily; The transverse passes underthe revolving knife or cutten An adjusting screw 62 permits regulatingthe pressure of the roll 60. v Y

'lhe numeral 63 denotes the revolving knife or cutter blade, which ismounted on a rotary drum 64, the latter being mounted in the stand 65.Said revolving knife co-acts with a stationary blade 66. The revolvingblade 63 is adjustably attached to its drum by bolt and slotconncctioiis'67 as shown in Fig. 5, while the stationary blade 66 isalso adjustable by the adjusting screws 68 and bolts 69. The relative sfieer l oij're volution ol' the revolving knife is also adjustable forthe purpose cl varying the lengths of out. For this puriose, the drum 64carrying the reknife is driven from a shaft 70, the latter having fastthereon an" expansible' pulley 71 which is expanded or contracted bymeans of the hand-wheel 72. Said expansible pulley 71 is driven by abelt 73 from a pulley 74, said belt 73 having sufficient slack toaccommodate variations in size of the pulley 71, and such slack beingtaken up by a suitable adjustable pressure-roll 75. I t is obvious thatthe expansion and contraction.

of the pulley 71 will vary the speed of rave lution of the knife 63. Asthe materialis cut into lengths, it falls upon an endless conveyer belt76 and is delivered thereby upon a' table 77. a i

Thusis completed, in a continuous opera tion, the'suc'cessive processesof corrugating' one or more sheets of paper at a time, running one ormore facing sheetsas desired, pasting them to ether, drying thecomposite sheet or i'naterialin transit and while pressing it out flat,and slitting, scoring and cutting the material into desired lengths.

and maintaining t e f9? on V I the stub" shaft 981s a spur-wheel or gearIt is understood that the several nn-rcl'nni isms hereinbefore mentionedare positively driven for the pur ose of feeding the paper roperrelative timing of the mechanisms. ower may be applied by any suitablemeans and the machine may be driven either in sections, or themachinemay as a whole be connected with a single source of driving power, thelatter being piw ferred. For this purpose I have represiml ed suitabledriving mechanism shown in elevze tion in Figs. 9, 10 and 11, and inplan view in Figs. 6, 7 and 8.

In Fig. .9, the numeral 80 dcnoLes a driving shaft from which power istransmitted by a belt 81 to apulleySQ oh a shalt 83, said pnl h* 82being preferably loose on said shaft 63 and adapted to belooked'thercwith by nit-ans of any suitable clutch (not shown), whichclutch may be operated by a starting lever 84, shown in Figs. 2 and 6.

Referring to the first section of the ma-- ohine, comprising thecorrugatingmechanisms, paste-rolls and pressrolls, it will be observer.from Figs. 6 and 9 that the shal 'ts ol' the first set of corrugatingrolls 8, 9 and .10 are provided with intermeshing gears 85. The' shaitsof the second set of rorrugniing rolls- 16, 17 and 18 are similarly prrividml with intermeshing gears 86. Between the two sets of gears 85, S6,and n'ieshing with om gear of each set, is a large spru- 87 on the shaft83; whereby power is coinnnnlirated lo the two sets of corrugatingrolls.

and at the opposite side (Fig. 3) said shaft 103 is connected bysprocket and chain gearing 104 with the stub shaft 105 of the spur 42for the upper drying belt. Similarly, referring to Fig. 10 again, thelower stubshaft 101 is connected by sprocket and chain gearing 106 witha lower shaft 107 which extends transversely below the under dryin belt,and at the opposite-side (Fig. 3) sai shaft 107 is connected by sprocketand chain earing 108 with the shaft 109 of the spur 42 for the lowerdrying belt. It is noted that there are no axial connections between thespurs 42 at the oppositesides of the drying -'apparatus, thisarrangement being necessary in order to permit the flexible hosesections 47 and pipes 44 and 46't0 pass between the driving spur-wheelsas the drying belts make the turn.

- The press-rolls 33, shown in Fig. 3, are, as shown in Fig. 10,provided with intermeshe ing gears 110 and driven by a sprocket chain 111 from a shaft 112, the latter being driven by a sprocket chain 113from the shaft 101.

Said shaft 101 (Fig. 10) also communicates powerby chain and sprocket gearing 116 to the cutting mechansim shown inFigs. 4 and 8 as follows: The sprocket chain 116 engages a gear orsprocket wheel 117 (Figs. 8 and 11) on the shaft 118. it the op ositeend of said shaft 118 is the pulley 74 Fig. 4) which drives by belt 73the before mentioned expansi'ble and contractible pulley 71. The shaft70 of said expansible pulley 71 is (as shown in Figs. 8 and 11) providedwith a gear 120 meshing with. a gear 121 on the sh aft of the revolvingknife or cutter 63.

The slitting rolls and 53 (Figs. 4 and 8) have their shafts providedwith inter- .igs. 8 and .11) and are driven by a sprocket chain 123 froma pinion on the shaft of one of the gears 114. From the slitting rolls122 power is communicated by a sprocket chain 124 to the shafts of thescoring rolls 54 and 55, the latter being also provided withintermeshing pinions 125.

From the scoring rolls, power is communicated by a s rocket chain 126 tothe shaft of the press ro 60.

It is understood that the foregoing description of the dryingconnections is made only with reference to the illustrated mechanism,since, as aforesaid, power may be supplied to the various parts of themachine by an suitable connections.
